Consider the streamlines over a circular cylinder as sketched at thefigure 3.26. single out the first three streamlines flowing over the topthe cylinder. designate each streamline by its stream function, vivianav3. the first streamline wets the surface of the cylinder, designate vanthe streamline above that is v2, and the next one above that is v3.assume the streamlines start out in the freestream equally spaced. hencethe volume flow rates between the streamlines are the same. thestreamline v2 passes through the point (1.2r,1/2) directly above the topof the cylinder. calculate the location of the point directly above the top ofthe cylinder through which the streamline y3 flows. comment on thespacing between the streamlines directly above the top.

Aforce of 34n stretches a very light ideal spring 0.73 m from equilibrium, what is the force constant (spring constant) of the spring? (a) 47n/m (b) 38n/m (c) 53n/m (d) 25n/m

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s
